Polyplastics Group, an engineering thermoplastics firm, has launched DURAST Powder know-how, which transforms high-performance resins into superb powders, enabling using various manufacturing processes from prototyping to 3D printing and mass manufacturing.
DURAST Powder know-how efficiently micronizes high-strength, high-molecular-weight resins – which had been beforehand tough to powder – into numerous shapes reminiscent of spherical or fibrous kinds primarily based on utility necessities. Specifically, high-performance resins like liquid crystal polymer (LCP) and polyphenylene sulfide (PPS) confronted challenges with typical grinding strategies, reminiscent of particle agglomeration and decreased flowability. Utilizing Polyplastics’ proprietary know-how, DURAST Powder achieves uniform powderization with a mean particle measurement of roughly 1~100 μm for LCP. This powder reveals glorious powder flowability and mixing dispersibility, contributing to course of stability and improved high quality.
Resins reminiscent of polybutylene terephthalate (PBT) and polyacetal (POM) pose vital challenges by way of micronization because of their low glass transition when processed by way of typical grinding strategies. Within the case of PBT and POM, the glass transition temperature (the temperature above which resin softens) is low, inflicting the fabric to simply agglomerate because of friction warmth throughout grinding. The brand new approach has efficiently enabled the powderization of those high-molecular-weight resins. When contemplating the thermal and mechanical properties of those resins and choosing powderization strategies fitted to every, the know-how produces powders with particle sizes starting from 20μm to 100μm with a slim particle measurement distribution.
DURAST Powder is appropriate for additive manufacturing utilizing sintering, enabling the manufacturing of complicated shapes and high-precision components. Moreover, it’s anticipated to be utilized as a matrix resin for carbon fiber-reinforced thermoplastics and as an natural filler or reinforcing materials.
